To build an aerobic system waste treatment on board ships is more pressing than ever. No longer can ships dispense their food and sewerage overboard. To do so will incur large fines from the next port they arrive at.
A food waste digester is needed to treat left overs and kitchen waste generated on board. The aerobic capacity needs to be balanced against the capacity of the crew and passengers. Also a place to store the biodigester as near to the kitchens as possible.
In 2014 it was estimated 1 billion gallons of sewage was released into the sea off America by Cruise ships
A 3,000-passenger cruise ship (considered an average size, some carry 5,000 or more passengers) generates the following amounts of waste on a typical one-week voyage:
- 1 million gallons of “gray water” i.e. shower, sink, dishwasher, washing machines
- 210,000 gallons of sewage.
- 25,000 gallons of oily bilge water.
We developed several years ago a system to break down effluent waste as well as kitchen waste effectively and quickly within the bowls of a ship. This allows a ship to continue for longer at sea without the need to attend port.
A range of products have been developed to meet ships of all sizes.
